Google co-founder Sergey Brin, who appeared at the TED stage yesterday, explained that smartphones don't allow their users to interact enough with the outside world, and even called them "emasculating." People walk around with their faces buried in their smartphone's screen and swipe at a piece of glass.

"Is this the way you're meant to interact with other people?" asked Brin. "It's kind of emasculating. Is this what you're meant to do with your body?

"When we started Google 15 years ago, my vision was that information would come to you as you need it. You wouldn't have to search query at all."

According to Brin, Google Glass -- a hands-free, voice-activated headset with augmented reality features -- is that vision materialized. Brin showed Google Glass off at TED, saying it's the way people were meant to interact with one another while still using digital technology.

Google Glass is being offered to early adopters right now for a steep price of $1,500.

1. Recording pics and movies on the go without having to hold and point a camera or phone + 1st person perspective. To actually get good optical quality it might require some pretty odd looking glasses, but OK, that's a decent point. No need to actually "aim the camera." You get what you see (almost).

2. Navigation without eyes leaving the road. Miss your turn and no-where to pull over and heavy traffic? Google, Navigate home. Done. In general , this improves everything about NAV. Your eyes still leave the road. The navigation may be "more in front of you" than before, but you still have to shift your eyes focus to it. Even laying it atop your vision requires a focus shift, and can lead to obscurring your vision as well. Nevertheless, it is an interesting place to go towards.

3. Browsing on the go. How do you input the websites and search queries you want, because I don't want to be walking around yelling out everything I'm doing.

4. Gaming on the go. Gaming with no input, and extremely weak graphics, sounds very exciting

5. Recording videos and no-one else knows its recording. Because that's not a huge privacy concern. I don't want people recording me without my knowledge.

6. Its a HUD like a video game. Not sure if this is a "cool factor" thing or what, but that's kind of subjective as to whether or not someone would like that. I believe some people may dislike such a thing because it would simply obscure portions of their vision without being easily adjustable on the fly. With my phone I can just look at it until I'm done.

Now I think this has huge potential, but I think the arguments you laid out for it are rather weak to be honest. You've provided me with very little reason to stop using my phone. I can't wait until I'm talking to someone and they're just looking at something while I'm talking. At least with a phone I can easily tell they're being a jerk and ignoring me.

Gaming on the go? That's a joke. What's the input device? You realize a device like this will have extremely limited processing power due to it's size and weight. It's more useful as an information terminal. Maps, diagnostics, recording and playback, and some uses I can't even imagine.

When tablets and phones became a commodity we got all sorts of cool uses out of them but they haven't really replaced many devices and probably won't.

I don't ever see glass as a gaming device. At least not on the glass, maybe as a terminal connected to a more powerful device.

2. You are criticizing HUDs in general with those remarks. HUDs arent perfect but they are very close. It only takes milliseconds to shift focus from a HUD and back. It takes longer to glance down at your speedo or fuel gauge. By your logic such acts must surely also be dangerous. Yet they happen millions of times a day and I seriously doubt anyone has ever crashed cuz they was looking at their fuel gauge lol.

3. Dont worry we're only about 5 years away from a commercialized subvocal interface. Such an interfacewill doubtlessly end up in Glass. Then nobody will hear you dictating commands to your device, or even having conversations with other people.

4. Dont criticize the graphics until you actually see them. Same goes for the interface. The potential is certainly there. You can make extremely precise analog movements with the eye.

5. Yeah but it is going to do wonders for fighting police corruption.

6. It would be easily adjustable. In theory you could move the HUD around your peripheral vision by making use of whatever binary interface option they end up using. (Binary meaning a button or a vocal command in combination with an eye gesture)

2) I wasn't trying to imply that it was inherently more dangerous, I was implying that it doesn't fix anything. Having the navigation in your peripherals or just stuck to the window/in the dash still requires changing focus of where you're looking, little improvement.

3) Uhm, you have nothing at all to back this up. "Trust me, it'll happen" is far from proof of concept. Extremely weak point, sir.

4) I will criticize the graphics because I know what's capable in what form factor. I work with graphics all day, and the device would be bulky and power consuming to get even simple games like angry birds working.

5) This is not justification for such a feature.

6) This is one I can't really provide an argument for or against until I see it working.
